    Comments about Shimano XT M770 9-Speed Cassette:

    Great Cassette, pretty good price. Lightweight, durable, I run these on two of my wheelsets (Shimano and Mavic), and an XTR on my Easton Havens. The XTR is a few grams lighter, but the performance on this is 99% of the performance of an XTR while being a fraction of the cost, and lasting several times longer. The best "all around" cassette Shimano makes in my opinion.

    Comments about Shimano XT M770 9-Speed Cassette:

    The version with the 4 spoke star holing the bigger sprockets together has problems. I read several reviews and experienced the problem myself: The second to largest sprocket bends like butter on moderate to steep climbs. Some users reported the problem was caused by shifting down when climbing, however, I managed to bend the sprocket just as the incline got a bit steeper.
